Is it mandatory to use the spacings specified in the National Electrical Code (NEC) or Canadian Electrical Code (CEC) for BreathSaver™ conduit?
No. BreathSaver™ conduit is not yet listed or certified for use in applications in accordance with the National Electrical Code (NEC) or Canadian Electrical Code (CEC). Therefore, for applications outside of the NEC or CEC, you can space hanger supports much further apart for BreathSaver™ conduit than for PVC. FRE Composites publishes a hanger span and deflection table in its BreathSaver™ catalog, which will guide you through your project or installation.
